NEVER AGAIN FARMER'S FLOOR IS A NIGHTMARE HARVEST 10,000 square foot concrete floor in his utility building began to crack and spall, he knew there was more to the f loor's premature failure than simple "bad luck." But the failure's fix yielded a crop of lessons that all involved won't soon forget. Y A successful Midwestern farmer — with approximately 5,000 arable acres — had built what he modestly describes as a "tool shed" to store and repair his large ride-on John Deere farming equipment, tools, and other supplies. However, at 10,000 square feet, the BY FLOYD DIMMICK SR. AND JENNIFER KRAMER PHOTOS COURTESY OF BODYTEK COATINGS GROUP AND CROWN POLYMERS ou've heard of the "Farmer in the Del l ," right? Wel l , this farmer was in "f loor- ing hell." When the year-old building is something more than a simple "shed." Two sides of the build- ing open in a manner akin to a garage door to allow the large farming equip- ment to pass through.

Instead of creating a smooth surface, it had the opposite effect, leaving deep grooves up to 3/8" in the concrete floor.

So, the farmer contacted Bob and Jeff Adney of BodyTek Coatings Group. Problems Keep Cropping Up "When we got there, it was easy to see at least one of the causes of the problems," recounts Jeff Adney. "The concrete floor was unsealed." Given the building's intended use — the storage and repair of heavy equipment and farming supplies, it was a puzzle why the floor was not properly sealed or overlaid.
